3.5*Hello_interval. If the configured holdtime is less than the current hello_interval , this
configuration is denyed. Every time hello_interval is updated, the Hello_holdtime will
update according to the following rules: If hello_holdtime is not configured or
hello_holdtime is configured but less than current hello_interval,hello_holdtime is
modified to 3.5*hello_interval, otherwise the configured value is maintained. The
command can configure on IPv6 tunnel interface, but it is successful configuration to only
configure tunnel carefully.
Example:
Configure vlan1’s Hello Holdtime to 10s
Switch (Config)# interface vlan1
Switch (Config -if-Vlan1)#ipv6 pim hello-holdtime 10
18.2.3.7 ipv6 pim hello-interval
Command: ipv6 pim hello-interval <interval>
no ipv6 pim hello-interval
Function:
Configure the interface’s hello_interval of pim hello packets. The “
no ipv6 pim
hello-interval
” command
restores the default value.
Parameter: <interval>
is the hello_interval of periodically transmitted pim hello packets’,
ranges from 1 to 18724s
Default:
The default periodically transmitted pim hello packets’ hello_interval is30s.
Command Mode:
Interface Configuration Mode
Usage Guide:
Hello messages make pim switches oriente each other and determine
neighbore relationship. Pim switch annouce the existance of itself by periodically
transmitting hello messages to neighbores. If no hello messages from neighores are
received in the certain time, the neighbore is considered lost. This value can’t be greater
than neighbore overtime. The command can configure on IPv6 tunnel interface, but it is
successful configuration to only configure tunnel carefully.
Example:
Configure vlan’s pim-sm hello_interval.
Switch (Config)#interface vlan 1
Switch(Config-If-Vlan1)#ipv6 pim hello-interval 20
18.2.3.8 ipv6 pim ignore-rp-set-priority
Command: ipv6 pim ignore-rp-set-priority
no ipv6 pim ignore-rp-set-priority
Function:
When RP selection is carried out, this command configures the switch to
enable Hashing regulation and ignore RP priority. This command is used to interact with
older Cisco IOS versions.
Default:
None
Parameter:
None
